I'm guessing I use the codes of the original head unit on the donor unit then somehow flash my car's VIN but I can't find any info on exactly what to do. When swapping them out the donor unit is stuck on the "BMW" logo screen but with radio static (the volume knob works).Ĭan someone provide a little guidance as to what to do next? I've been searching the forums for days but cannot find guides on coding/registering a different unit that's registered to another VIN. My L7 Basic CD unit (Rear Camera, PDC, No Nav, BT Phone only) kept rebooting and was unresponsive (all controls such as Volume and IDrive controller freeze after a second) so I decided to buy a similar unit (I assume they are compatible although donor unit, from a 1 series I believe, says "Entry CB" on sticker while the original unit says "Entry CB RFK") on Ebay to replace it. Car is 2012 F31, HU is CIC as far as I can tell and there is no Combox in the rear.
